Scientists discover how molecular motors go into 'energy save mode'

The transport system inside living cells is a well-oiled machine with tiny protein motors hauling vital cargo around the cell. A new study describes how the motors save energy, when their transport services aren't required. The solution to this molecular puzzle provides new insight into how molecular motor proteins are regulated, and may open new avenues for the treatment of various...

Next Generation 9-1-1 Would Provide More Data

A fire has started in your dryer, and you call 911. In addition to hearing your frantic description, the 911 operator also automatically logs your location and receives live video from you of the smoke emanating from your dryer. That vision of a multimedia 911 could become commonplace following the implementation of a new plan by the Federal Communications Commission for the development of Next...

HTC Bets $300M on Better Sound from Dr. Dre's Company

HTC has invested a reported $300 million into a strategic partnership with Beats Electronics. Beats is best known for its Beats by Dr. Dre audio product. The aim of the partnership is to bring high-performance sound to HTC mobile devices. HTC and Beats have been working to create high-quality mobile-audio experiences. The smartphone market will see the fruit of those labors in a new line of HTC...

Permanent HP Price Cut Helps Fuel Tablet Market

After Hewlett-Packard lowered the price of its TouchPad by 20 percent, a new report says cheaper devices with fewer features are fueling a surge in the tablet market. "De-featured, low-cost media tablets are being introduced by more than 50 vendors in 2011," said ABI Research mobile-devices group director Jeff Orr. "This will certainly help bolster year-over-year growth for the category, but it...

Engineers redefine how the brain plans movement

New neurological measurement technologies and algorithms are allowing researchers a more complete look into how the brain functions. Engineers are using these tools to better understand how the brain prepares to initiate a body motion and why sometimes we react more quickly than...

Catalyst that makes hydrogen gas breaks speed record

Looking to nature for their muse, researchers have used a common protein to guide the design of a material that can make energy-storing hydrogen gas. The synthetic material works 10 times faster than the original protein found in water-dwelling microbes, the researchers clocking in at 100,000 molecules of hydrogen gas every...

Intestinal protein may have role in ADHD, other neurological disorders

A biochemical pathway long associated with diarrhea and intestinal function may provide a new therapeutic target for treating ADHD (Attention Deficit Hyperactivity Disorder) other neuropsychiatric disorders, according to scientists. Researchers discovered the pathway's key protein is also expressed in critical areas of the brain and its activity helps regulate attention and activity level in...

Supernovae parents found

Observations of Type Ia supernovae has led to the discovery that the universe is expanding at an accelerating rate and the notion of dark energy. However, astronomers do not know for certain how the explosions take place and whether they all share the same origin. Now, a team of researchers has examine 41 of these objects and concluded that there are clear signatures of gas outflows from the...

Stick-on tattoos go electric: Micro-electronics, elegant design and existing tattoo tech combine to create complex device

Through a combination of careful theoretical modeling and precise micro-manufacturing, a team of engineers and scientists has developed a new type of ultra-thin, self-adhesive electronics device that can effectively measure data about the human heart, brain waves and muscle activity -- all without the use of bulky equipment, conductive fluids, or...

New Look at Exploding Stars Provides Cosmic Yardstick (SPACE.com)

SPACE.com - In universe spanning more than a billion light-years, distance can't be measured with a ruler. To judge how far away objects are, astronomers must rely on other objects whose properties are already known — such as certain kinds of exploding stars called supernova.  

Superfast Military Aircraft Lost in Test Flight (SPACE.com)

SPACE.com - The U.S. military lost contact with an unmanned hypersonic glider shortly after it launched on a test flight today (Aug. 12) as part of a global strike weapons program to develop vehicles capable of flying at Mach 20 and reach any target in the world in an hour.
